Abstract

Crystal and solution structures of the [Pd^II^(η^3^‐allyl)] and of the [Pd^II^(η^3^‐1,3‐diphenylallyl)] complexes, 4 and 5, respectively, with (4__S__)‐4‐benzyl‐2‐[2′‐(diphenylphosphino)phenyl]‐4,5‐dihydrooxazole (3) were determined by X‐ray crystallography and 2D‐NMR spectroscopy. Complex 4 proved to be disordered with both diastereoisomeric complexes in the crystal. The results of X‐ray and NMR experiments demonstrate a good agreement between solution and solid‐state equilibria of the two isomers. A comparison with dichloro{(4__S__)‐2‐[2′‐(diphenylphosphino)phenyl]‐4,5‐dihydro‐4‐phenyloxazole‐P,N}zinc(II) (2b) shows a surprising conformational stability of the coordinated phosphinooxazole ligand 3.
